RE: Seaport Roadshow IPO Prospectus28 Apr 2026 07:50
Pre IPO, there are 38.8 million shares to which Puretech own 35.1%. That equates to 13.6 million shares. With the raise of $200 million at $17 per share, there will be 50.6 million shares. Without Puretech contributing anything to the IPO, they will be diluted to 26.8% of Seaport worth $231 million (at the midpoint IPO price of $17).
Someone please tear me apart if I’ve got these numbers completely wrong.
